At different times when attempting to park the truck, the brake pedal becomes very stiff (hard). I had to apply both feet to the brake pedal to stop the truck. This occurred twice in the past month. Contacted GM and was told that there is no recalls on this issue. I checked the internet and discovered that other Silverado and Sierra owners are having the same problem. There needs to be a recall before someone is injured or dies because of this issue! in both cases I was driving at low speeds and in the process of parking the truck in my driveway and at home depot.

Brake booster went out at slow speeds. Was backing up and noticed brakes were hard to push. Pulled forward and the same thing. Once I started to drive the problem went away. Very hard brake pedal after driving around parking lot. Car had to be less than 3mph for problem to occur.

Loosing brakes starts when moving backwards I have to put both feet on pedal to stop, then does same thing when moving forward. Doesn't do it all the time but you never know when its going to happen. Started at about 29000 miles have about 29500 on it now haven't driven in a few months

2014 Chevrolet Silverado multiple recalls on this vehicle and just received a letter about the faulty vacuum pump for the braking system. Been having issues with mine for over a year, but apparently it's only covered by the manufacturer if it's under 72K miles. Either it's a manufacturer fault or it's not. My being over 72K makes it 'my problem' I suppose. Sad they are allowed to get away with this.

Takata recall - tried parking today and backed into my parking garage wall at work - no damage to vehicle but scared me quite a lot to all the sudden lose complete control of my brakes - pedal became stiff - would barely move no matter how hard I pressed it and then brakes stopped working completely. All the forums I am reading is related to vacuum pump. This is a joke that this hasn't been recalled yet. These geniuses are waiting for someone to get killed before they are going to fix it apparently. Truck is 2014 Silverado 1500 ltz Z71 with only 29,000 miles on it. Sure as hell is just out of warranty period.

Suspension makes noises when turning or going over bump. Driver seat feels like it moves/shifts slightly when making a turn. No brake pedal or 'rock' hard brake pedal at low speeds, in traffic, or when in reverse.

- Ft Stewart, GA, USA

Brakes became hard to push and truck wouldn't stop. It started off when backing into a parking spot and then driving forward slowly. That was last fall. Now the brakes are hard to depress all the time, and sometimes have to use both feet. Brought it to mechanic shop and it is the brake vacuum pump.

I lose power brakes while driving especially at slow speeds the pedal gets very stiff to where I can almost not even stop. It even started getting worse at high speeds now

- Charles City, VA, USA

While driving downhill on a local highway, another vehicle changed lane into my lane which forced me to brake to avoid a collision, but brake pedal was very stiff and required more force than usual to apply the the brakes. Fortunately, I did not hit the other vehicle and but had to pull over to a parking lot check on my family who were shaken up about the ordeal. I turned off the vehicle for a few minutes to see if it resets the problem but after starting the vehicle and driving it around the parking lot a few times, the problem was still there and a brake assist service message was now showing.

Brakes became hard to push down and could barely stop. Luckily I was backing into a parking space at work and the sidewalk ledge stopped me. Now when I try to stop the brakes will only push down about an inch then are almost impossible to push down to stop. From what I read online the problem is likely the vacuum pump.

Brakes engaged and locked up while driving during normal road conditions in July 2018.towed to dealership & problem was the braking module. However, 6 months later and the brakes engaged and lock up again while driving on normal road conditions. Towed to dealership & this time they determined the booster valve controlling the brake fluid was the issue. 2 days later, the brake assist engaged while driving and the brakes locked up again. Had to depress the brake assist button multiple times to get it to release. These instances are occurring while road conditions are bare & temps are above freezing. This is dangerous since brakes lock up while in the middle of traffic traveling anywhere from 30 mph to 50 mph.

When trying to stop at low speeds the brakes act like loss of power brake and have at least 5 times almost hit a car in front of me because couldn't stop. I took it to the local GM dealer and had it repaired and it was the vacuum pump, and after finding out the problem I found on the web that there is a big problem with this on 2014-2018 GM trucks and was advised to file a complaint because it is a huge problem and should be recalled, especially after it cost me over $800. I have around 72,000 miles and looking on the web quite a few have had this problem as early as 10,000-30,000 but was taken care of under warranty and probably weren't reported

At low speeds, the brake pedal becomes hard/impossible to press and does not slow down the truck. It feels as if I have no control over stopping the vehicle. This seems to be happening to a lot of owners of these trucks according to what I am seeing while researching the issue.

- Moncks Corner, SC, USA

At low idle the brake assist does not work. I have to push very hard on the brake to stop. In city stop and go traffic it's impossible

At low speeds or idle, power brakes are lost requiring to use emergency braking to prevent collisions.

- Landisburg, PA, USA

Brake pedal becomes hard after pressing 2 or 3 times when engine is at or near idle resulting in absolutely zero braking ability. Occurs in both forward and reverse. Resulted in having to use the emergency brake in order to prevent a collision.
